The concept is full of electronics and LED lamps everywhere (including 3D monitor), so it weighs 75 kg more than the standard CSR - 635 kg, even though the whole car is fully made of CF. AeroSeven uses 2.0 Duratec engine, which is enough to get 236 bhp @ 8500 and 206 Nm. So the p/w ratio should be close to 400 bhp/tonne. And the power is sent via 6-speed manual to RWD. Two modes are available - Road and Race. Sounds like lots of fun and performance, but 0-100 time doesn't sound too much impressive - 4.0 sec.

The body is made to be maximally aerodynamical and downforce (it doesn't even have a windshield!; thankfully, it's got the mirror!). That, of course, benefits, but I'm not a fan of the modern design. IMO, it looks like a polished soap-box with Christmas lights, kind of awful; Caterham for teenagers... I prefer the classy original Seven.

Caterham is considering putting this car to production in 2014. Well, it would be a perfect competitor to the Vuhl 05.

Want something new from Caterham stable? Then you might like this:

Caterham and Renault signed an agreement in co-operation and development of new models. Have you ever heard of rumored Alpine successor? Yes, that means Caterham will have its own sportscar based on the Alpine. I guess Caterham's car will be underpowered in comparison to the Alpine, whether Renault is the "chief". But we will see details further.

But that's not all. Not just Caterham is developing Alpine's cousin, but CaterHam also is planning to expand its model range with the SUV and city car for Asian market! That's ridiculous! The company, famous for some of the fastest track cars, will build chick cars based on Renault platform! I'm not willing the Caterham becoming a consumer goods...

The ultimate 7. 620R. It replaces the old Superlight R500. But this car is the new step. If the previous one produced 260 horses, this one is boosted up to 310 horses. That's a lot! And so 620R can creates amazing 620 bhp/tonne (the name is obvious). That number is practically the same as Veyron's SS! So you can expect some really fast laptimes. And top speed - 250 kph, 0-100 in just under 2.8 seconds. Blitz!

The price for this toy is £50k, which is about $75k. That's a lot for a car that does not even have a roof. But if you're looking strictly on track performance, that's the best bargain.
